Michael Clarke has been reprimand for making a DRS 'T' signal while captaining New South Wales against Tasmania.

The incident occurred on the second day of the Sheffield Shield clash, when a Tasmania batsman was given not out when New South Wales claimed a low catch in the gully. Clarke then made the 'T' signal towards the umpire, which is used in international cricket to ask for the review system to be utilised.

Cricket Australia has amended their code of behaviour to make it automatic dissent if a player, whether in jest or not, uses the 'T' sign during domestic cricket where the DRS is not available. Clarke admitted guilt and accepted match referee Daryl Harper's proposed penalty of a reprimand so a hearing was not required.

Clarke made 88 on the first day of the match, his first innings since the one-day series against England following a flare-up of his long-standing back problem, but had less success in his second innings - bowled for 7 by a delivery from Ben Hilfenhaus which nipped back - although the Blues were handily placed to claim victory after setting the Tigers a target of 295 which would be the highest total of the match.

By stumps, the Blues had already claimed one wicket in the eight overs available with Josh Hazlewood removing Ed Cowan to leave the Tigers 1 for 18.

The visitors had begun the day significantly behind in their first innings, but closed the gap as the final-wicket stand between Luke Butterworth and Sam Rainbird extended to 56, cutting the deficit to 49. They then chipped away at the beginning of the Blues' second innings and when Clarke departed the home side were 3 for 77.

However, Steve Smith (63) and Scott Henry (65) added 114 in 26 overs to stabilised the Blues' position before the Tigers came back strongly to claim the final seven wickets for 54. The left-arm spinner Clive Rose and seamer Evan Gulbis took seven scalps between them.
